what do you think about dropping the `--geometry' command line option
from abiword?

IMO nowadays there are better ways to do this (wnck) on platforms
where launching from command line is not totally exotic (gtk).

This would also remove the last remaining X Window System dependency
(XParseGeometry) from the codebase. I have a patch to replace it by
gtk_window_parse_geometry(), but is this command line arg really
needed in the first place?
